-Control GCC's optimizations to provide a safe compilation for live-patching.
+Control GCC's optimizations to produce output suitable for live-patching.
 
 If the compiler's optimization uses a function's body or information extracted
 from its body to optimize/change another function, the latter is called an
 impacted function of the former.  If a function is patched, its impacted
 functions should be patched too.
 
-The impacted functions are decided by the compiler's interprocedural
-optimizations.  For example, inlining a function into its caller, cloning
-a function and changing its caller to call this new clone, or extracting
-a function's pureness/constness information to optimize its direct or
-indirect callers, etc.

 Usually, the more IPA optimizations enabled, the larger the number of
 impacted functions for each function.  In order to control the number of
-impacted functions and computed the list of impacted function easily,
-we provide control to partially enable IPA optimizations on two different
-levels.
